Detailed description of the invention
Shown in seeing figures.1.and.2, the rectilinear motion feed arrangement that an embodiment of the present invention provides mainly comprises ball-screw 1, be arranged at feed screw nut seat 2, clutch shaft bearing seat 3, second bearing block 4 and bellows coupling 5 on ball-screw 1.The cooperation of ball-screw 1 and feed screw nut seat 2, by the rotary motion of drive unit, can be converted into the rectilinear motion of feed screw nut seat 2.
Clutch shaft bearing seat 3 tubulose, its aperture is greater than the diameter of ball-screw 1.It is inner that first needle roller-cylindrical roller thrust combination bearing 6 is arranged at clutch shaft bearing seat 3, and on the inwall being fixed on clutch shaft bearing seat 3 by screw 7.The left end of ball-screw 1 enters clutch shaft bearing seat 3, can be set on it closely to make the first needle roller-cylindrical roller thrust combination bearing 6.One end of clutch shaft bearing seat 3 is provided with spacer ring 10, and its aperture can make the left end of ball-screw 1 enter, and is fixed by screw and the first needle roller-cylindrical roller thrust combination bearing 6.During installation, spacer ring 10 and clutch shaft bearing seat 3 form labyrinth seal, are sealed in clutch shaft bearing seat 3 by the first needle roller-cylindrical roller thrust combination bearing 6.
Bellows coupling 5 is arranged at the inside of clutch shaft bearing seat 3, and its one end is connected to the left end of ball-screw 1 by accurate locking nut 7, and the other end stretches out clutch shaft bearing seat 3 slightly.
The outer setting of clutch shaft bearing seat 3 has motor 8 and planetary reducer 9.One end that motor 8 stretches out clutch shaft bearing seat 3 by planetary reducer 9 and bellows coupling 5 is connected, to be conducted to ball-screw via bellows coupling 5 by the power of motor 8.
For the ease of maintenance, the tube wall top of clutch shaft bearing seat 3 has opening 11, and its position is corresponding to the bellows coupling 5 being installed on clutch shaft bearing seat 3 inside.Opening 11 installs cover plate 12 by screw.When needs overhaul bellows coupling 5, only need to open cover plate 12.
Second bearing block 13 is similarly tubulose, and its inside is provided with the second needle roller-cylindrical roller thrust combination bearing 14.The aperture of the second needle roller-cylindrical roller thrust combination bearing 14 is suitable with the diameter of ball-screw 1 right-hand member, can be set on the right-hand member of ball-screw 1 to make the second needle roller-cylindrical roller thrust combination bearing 14.
The right openings of the second bearing block 13 is sealed by pressing plate 15.Second needle roller-be provided with spacer ring 16 and accurate locking nut 17 between cylindrical roller thrust combination bearing 14 and pressing plate 15.Spacer ring 16 and accurate locking nut 17 are sheathed on the left end of ball-screw 1.Second needle roller-cylindrical roller thrust combination bearing 14 and spacer ring 16 are fixed by screw 18.
The left side opening part of the second bearing block 13 is provided with the accurate locking nut 19 that can be sheathed on ball-screw 1, for by left side closure of openings.Be positioned at the ball-screw 1 part sheathed sleeve shaft bearing moving-coil 20 between accurate locking nut 19 and the second needle roller-cylindrical roller thrust combination bearing 14.The middle part of sleeve shaft bearing moving-coil 20 caves inward, and the aperture of two ends substantially in the second bearing block 13 is identical, but matched in clearance, to form gap I.The middle part of sleeve shaft bearing moving-coil 20 depression then forms cavity II with the hole wall of the second bearing block 13.In the second bearing block 13 bottom, offer the drain outlet III being communicated with cavity II and space outerpace.
When ball-screw 1 is under the drive of 8 of motor during High Rotation Speed, the gas mineralization pressure field in gap I and cavity II, intercepts fine particles such as dusts outside the aperture of the second bearing block 13.When ball-screw 1 stops the rotation, above-mentioned pressure field disappears, and the fine particles such as dust likely can enter in cavity II.But, when ball-screw 1 again High Rotation Speed time, the fine particles such as dust can be expelled to space outerpace via the drain outlet III be communicated with cavity II.
Still with reference to Fig. 1 and 2, the feed screw nut seat 2 of the rectilinear motion feed arrangement that present embodiment provides for being connected with moving-member 21, to make moving-member 21 can along with feed screw nut seat 2 is along lead screw straight-line.Clutch shaft bearing seat 3 and the second bearing block 13 are separately fixed on Digit Control Machine Tool.
In a preferred embodiment, the bottom of clutch shaft bearing seat 3 is horizontal " L " shape, and the fixed position 22 of itself and lathe has horizontal mounting surface A and vertical installation surface B, can carry out more stable installation location by screw.Second bearing block 13 can be installed on fixed position 23 by cushion block and voussoir.Certainly, should to take more appropriately according to the shape of fixed part 22 and fixed position 23, mounting means easily
With reference to shown in accompanying drawing 3, in other embodiment, on accurate locking nut 17, offer the hole for installing check pin 24.Check pin 24 is compressed by screw 25.This mode departed from that prevents is equally applicable on accurate locking nut 7 and accurate locking nut 19.
In addition, during installation, accurate locking nut 17 can be made to carry out pretension to the second needle roller-cylindrical roller thrust combination bearing 14, to make ball-screw 1 by prestretched.Or, make accurate locking nut 7 carry out pretension to the first needle roller-cylindrical roller thrust combination bearing 6, to make ball-screw 1 by prestretched.Again or, above-mentioned both carry out simultaneously.This setup, effectively can eliminate the play of the first needle roller-cylindrical roller thrust combination bearing 6 and the second needle roller-cylindrical roller thrust combination bearing 14, can compensate the thermal stretching of ball-screw 1 simultaneously.
As shown in Figure 4, in certain embodiments of the present invention, feed screw nut seat 2 has Part I 26 and Part II 27, and is provided with pad 28 between Part I 26 and Part II 27.Pad 28 is connected with Part I 26, is pressed on Part II 27 by axial pressing force.The thickness of pad 28 is more than or equal to the backlass of leading screw, and when reversely rotating to make leading screw, pad 27 can by the backlass between reverse tensioner elimination ball-screw 1 and feed screw nut seat 2.
Above various enforcement example of the present invention is described in detail.It will be understood by those skilled in the art that and when not departing from the scope of the invention (being limited by the accompanying claims), various amendment, change and change can be carried out to embodiment.Should explain from entirety the explanation of right and meet and consistent most wide region is described, being not limited to example or the enforcement example in describing in detail.
